IMPROVEMENT IN SIGNAL HEAD-LIGHTS.

' Specification forming part of Letters Patent No. 210,412, datedDecember 3, 1878; application liled October 28, 1878.

To all whom it mag concern:

Be it known that we, ANDREW DRESSELL, ERNST H. Vern, and JoI-IN G. Vern,of Cleveland, in the county of Onyahoga and State of Ohio, have inventeda certain new and 1mproved Head-Light for Locomotives; and we do herebydeclare that the following is a full, clear, and complete descriptionthereof, reference being had to the accompanying drawings, making a partof the same.

This invention relates to head-lights for locomotives, and has for itsobject the attachment to said head-lights of side colored lights forsignaling purposes.

The chambers of the signal or side lights are connected respectively anddirectly to each side of the head-light case, and so arranged inrelation to the head-light reflector that the light therefrom passes atonce into the chambers through openings in the side of the reflector,and corresponding openings in the said chambers. from which it isreflected by a mirror placed at the back of the chambers. The light thusreflected from the chambers is colored by its passage through stainedglass, the color being consistent with the signal, and changeable, asthe nature of the signal may require.

The invention is an improvement on a patent for head-lights granted tous April 23, 1878, No. 202,711.

A more full and particular description of the improvement will be foundin the following specification, and illustrated by the accompanyingdrawings, in which- Figure 1 is a front view of the head-light, havingattached thereto the side lights or chambers. Fig. 2 is a side view.Fig. 3 is a plan view; Fig. 4, a side view of the inside of thehead-light, and Fig. 5 a detached section.

Like letters of reference refer to like parts in the several views.

The head-light above alluded to is, or may be, constructed similar tothose in ordinary use 5 and mainly consists of a lantern or case,

A, reflector 13, provided with appropriateopenings for the chimney andlamp, said lamp the reflector B in the ordinary way. In each side of thereflector B is an opening, 0, Figs. 1 and 4, for the passage of lightinto the side chambers, D. Said chambers are connected directly to thesides of the head-light case, as shown in the drawings, so that thelight from the reflector B can pass at once into the chambers or sidelights, the chambers being in open relation to the body of thehead-light by openings made in the sides of the body A thereof. One ofsaid openings is shown at E in the door F, Fig. 4, of the head-light,which door is shown as open,. that the opening E and the inside of thehead-light may be seen. The opening E relatively corresponds to theopening (J of the reflector, so that when the door is closed the twoopenings will be in close proximity to and opposite each other, therebyallowing the light from the reflector to pass at once into the sidechamber or chambers, as above said, without the intervention of tubes orconduits.

The side lights, 1), above alluded to, consist of a chamber of the shapeshown in the'drawings, or a modification thereof. In the back of saidchamber is a mirror or reflector, G, Fig. 5, arranged at an anglecorresponding to the angle of the side H, Fig. 3, of the chamber, sothat the light passing into the chamber will be reflected therefromthrough the face I, Fig. 1, causing the light to be thrown forward andseen in front of the engine, as the rays are from the head-lights. Lightis also thrown from the side J of the side lights or chamber, said sidesbeing of glass, as seen at J in Fig. 2, and of the same color as theface-glass, so that the colored light or signallight may be seen fromthe sides as well as from the front of the engine. Reflectors or mirrorsmay be arranged in the side chambers at the bottom, top, or sides, otherthan the reflector last referred to, for the purpose of causing all thelight-rays to be thrown through the colored glasses of the sidechambers.

Access is had to the front and side glasses of the chambers, for theirremoval to be replaced by others of a different color; also, access ishad to the inside of the chambers by a door, K, which in Fig. 5 isrepresented as open.

The light from the reflector B may be shut olf from the side chambers bya slide, L, Fig. 4.

In our patent above referred to, the side chambers were attached to thesides of the head-light or lamp by a tube, by which they were extendedout from the sides of the main light; also, a tube extended from thereflector B of the head-light to said tube, connecting the side lightsor chambers to the main light, and into which tube the one from thereflector telescoped on closing the door of the headlight.

In practice it is found that the tubes are unnecessary; that equallygood results are obtained by dispensin g with them, and attaching thechambers directly to the sides of the head light case, as abovedescribed, thereby permitting the light from the reflector to passimmediately into the chamber, andnot through tubes, as set forth in thepatent alluded to. The expense, also, of the lamp or head-light is muchless, as its construction without the tubular passages is more simple,convenient, and equally eflicient. In the chamber of the side lights maybe arranged a mirror or re flector, for reflecting the light through theside windows or glass of the chamber.

What we claim as our invention, and desire to secure by Letters Patent,is-

In locomotive head-lights, the side lights or chambers, D, provided witha reflector, glass face and sides, constructed substantially asdescribed, and connected directlyto the sides of the head-light, and inopen relation therewith, and to the reflector thereof by openings 0 andE, respectively, as herein set forth, and for the purposes specified.
